This invention relates to car roofs ofthe type whereinthe metal roof sheetsare riveted together and to the tops of interiorcarlines along theiradj aeent margins. It has for its "L principalohjectsto produce a strong and a light Weight. roof oisirnple 'andeoonomieal n truc ion hat s. ea y of appli at o d that inayleak throngh thej of joints, or around the rivets at sec r h she t othe that will prevent any water reachingthe' interior of the'car. Other objec sare increase hes eng h a d rigid y. of the earlines andv to secure efiective venti lation ofthe car. The invention consists in 'ithe carmoof andi in the construct on, comhi nations, and. arrangements of :parts herein after described and claimed.

arlinejmernber is in the forrn olf'a sectlonal plate 7 of channel-shaped cro ss s'eo line and is rigidly secured to the base edges flanged up, as

' per or main carline member tion that extends the full length of the carflanges 6 of the upper carline member 5 and thus serves as a closure plate for the downwardly opening channel therein. jhe lower carline member 7 is wider than the upper or main carline member 5 so that its upstanding side marginal flanges 8 are located beyond and extend above the base flanges 6 of said upper carlinefmember. this arrangement, any water that gets under the lapped margins of the roof sheets or through the holes for the :rivetsQ onto the trough-shaped lower carline member or closure plate Swill drain lengthwise of said plate and will be discharged through the depending enos of the carline B outside of the car. In order to ventilate the car, the lower carline member 7 is provided with a series of holes 9 that are spaced apart lengthwise of said member and serve to permit air that enters the open ends of the carlines to reach the interior of the car. As shown in the drawings, the holes 9 are oi'i'set with relation to the rivets located thereabove and have their at 10, so as to prevent water that leaks through the holes for the rivets from entering the car through said holes. I

To facilitate assembly, the lower or bottom member 7 of each carline B is made in five sections of channel-shaped cross-section; namely, a ridge section 7 a, relatively long duplicate side sections 7 b and duplicate end or eaves sections The ridge section 7 a of the lower carline member 7 slopes downwardly from its middle toward its ends to conform to the slope of the underside of the upper carline'member 5 and is held in place beneath said upper member by extending the ridge end portions of the two'side sections 7 Z) beneath the adjacent ends of said ridge section. T he end sections 70 are of angle-shape and have one leg that is riveted to the base flanges 6 of the upper carline member 5 and extends beneath the adjacent caves end 0. the adjacent side section 76. The other legs of the end sections 7 c extend downwardly between the upstanding inner flange A f the side plates A and the depending end portions of the up- 5 and thus form the inner walls of the depending end portions B'of the carline B. In assembling the roof, the upper or main carline member 5 with the angular end lower carline sections 7 c thereon are attached to the side plates A, the lapped side margins of the roof sheets are then secured to the tops of said upper rline members by the rivets 2, and the side and ridge sections 711 and 76, respectively, are then cured to the base flanges 6 of said upper carline members and cooperate with the end sections 70 to form the bottom members or closure plates 7 of, the carlines B which function as drain troughs or channels for carrying away any water that may leak between the lVhat I claim is:
